ABSTRACT

PURPOSE: To evaluate the prevalence and significance of incidental non-cardiac findings (NCFs) on cardiac magnetic resonance imaging (MRI). We also aimed to assess the unreported rate and clinical significance of NCFs in official radiological reports.

MATERIAL AND METHODS: Consecutive cardiac MRI examinations of 400 patients were retrospectively analysed and MR images reviewed by 2 observers blinded to official radiology reports. NCFs were classified as insignificant, significant, and major. In patients with significant and major findings, NCFs were classified as previously known or unknown, based on clinical archive. Moreover, we investigated the clinical follow-up results of patients with major NCF.

RESULTS: Of 400 patients, 137 patients (34.3%) had a total of 175 NCFs. Fifty-nine NCFs were considered significant, and 23 were major. Patients with NCFs were significantly older than those without (p < 0.0001). Of 82 significant and major NCFs, 25 were previously unknown. In total, 18 significant and 4 major NCFs were unreported in official MRI reports. The unreported major NCFs were portal vein thrombosis, pulmonary nodule, pulmonary embolism, and liver nodule. The most common unreported findings were pulmonary artery-aorta dilatation and hiatal hernia. No statistical difference was found between official MRI reports and second consensus reading for the detection of major NCFs (p = 0.082).

CONCLUSIONS: The frequency of significant and major NCFs increases with age. Although no statistical difference was found between official MRI reports and second consensus reading for the detection of major NCFs, extra-cardiac findings should be carefully investigated during assessment.

ABSTRACT

Alzheimer’s disease (AD) is the most common type of dementia. The ε4 allele of the apolipoprotein E (ApoE) gene is the strongest known genetic risk factor for late-onset AD. Triggering receptor expressed on myeloid cells 2 (TREM2) is another important risk factor affecting the AD process after ApoE. Emerging evidence has identified TREM2 as a putative receptor for ApoE, raising the possibility that interactions between ApoE and TREM2 modulate the pathogenesis of AD. In this study, we performed molecular docking and molecular dynamics (MD) analyses to characterize the ApoE-TREM2 interaction and further investigated the effect of the major TREM2 disease-associated mutation (R47H) on the affinity of TREM2 for ApoE. The results indicate that the binding energy between ApoE and TREM2 occurs in an isoform-dependent manner with the following potency rank order: ApoE4 > ApoE3 > ApoE2. In addition, the R47H mutant reduced the interaction between ApoE and TREM2 protein, which may be attributed to decreased hydrogen-bonding interactions, hydrophobic interactions, and electrostatic forces between ApoE and TREM2. Our study analyzed the molecular pattern of the interactions between ApoE and TREM2 and how the variants affect these interactions based on in silico modeling, and the results might help to elucidate the interaction mechanism between ApoE and TREM2. Additional experimental studies will be needed to verify and explore the current findings.

ABSTRACT

PURPOSE: The objectives of our study were to evaluate the changes in the cross-section area of carotid and femoral arteries caused by fluid loss during haemodialysis (HD) and to determine the direction and amount of these changes.

MATERIAL AND METHODS: Seventy-four HD patients (28 women and 46 men) were studied. We performed ultrasound exams of the distal common carotid and proximal femoral arteries in each patient before and after a HD session. Recorded exams were analysed using EchoPac software. Arterial cross-section area values were acquired for further analysis.

RESULTS: We found a statistically significant decrease in arterial systolic cross-section area values after HD sessions (carotid arteries area before HD equalled 0.6731 cm² and 0.6333 cm², p = 0.00001 after HD, femoral arteries area before HD equalled 0.8263 cm² and 0.7635 cm², p = 0.00001 after HD). The decrease of systolic carotid cross-section area correlated with the amount of fluid lost during HD sessions (correlation coefficient of 0.3122, p = 0.010) and the percentage of the body mass lost during HD (correlation coefficient of 0.3577, p = 0.003). No statistically significant changes were found in the femoral cross-section area.

CONCLUSIONS: Our findings suggest that the arterial cross-section area may be used in the assessment of response to body fluid loss. We were able to measure changes due to fluid loss during the HD session. The carotid cross-section values decreased after the procedure and correlated with the amount of fluid lost during the HD session.

ABSTRACT

PURPOSE: We have investigated the technical and clinical success of percutaneous catheter drainage (PCD) in retroperitoneal abscesses and factors that may affect the outcome.

MATERIAL AND METHODS: The study cohort included 45 patients (17 females and 29 males, with mean age of 56.3 years) that were treated between 2012 and 2020. Forty-seven abscesses were managed with PCD under ultrasonography, computed tomography, or fluoroscopy guidance. Patients’ demographics, lesion locations, predisposing factors, clini-cal presentation, etiology, radiological findings, technical factors, and outcome parameters were presented using exploratory and descriptive statistics.

RESULTS: Abscesses were located in the psoas (n = 25, 55.3%), renal-perirenal (n = 7, 14.8%), and pararenal (n = 14, 29.7%) compartments. The mean preprocedural volume was 263.3 (30-1310) ml. Pain (abdominal and back) (57.4%) and fever (17%) were the most frequent presenting symptoms. The most common predisposing factors were previous surgery (n = 17, 36.1%) and diabetes mellitus (n = 11, 25.5%). Clinical success was attained in 89.3% of abscesses (definitive treatment 72.3% and partial success 17.0%). There was a statistically significant difference between the iatrogenic and non-iatrogenic groups regarding clinical success (p = 0.031). No mortality was encountered. The complication rate was 6.6% and were all minor. The average rate of recurrence was 10.6%. The mean time to catheter removal was 15.8 ± 13.2 days.

CONCLUSIONS: PCD is a safe and effective procedure in the treatment of retroperitoneal abscesses. Procedure-related mortality, morbidity, and complication rates are low. Underlying etiology is a significant factor affecting the outcome. Nevertheless, PCD may provide definitive treatment in the majority of patients.

ABSTRACT

PURPOSE: To ascertain the role of optic nerve sheath diameter (ONSD) in the evaluation of cerebral venous sinus thrombosis (CVST).

MATERIAL AND METHODS: A retrospective study with convenient sampling was done during the period November 2018 to January 2020. Forty-one patients across all age groups with magnetic resonance venography (MRV) diagnosis of CVST and 82 gender-matched controls were included in the study. ONSD was measured on axial T2-weighted magnetic resonance images. CVST was identified on axial TOF-MRV including the stage, degree, and location. Intraparenchymal infarction and haemorrhage were also noted with their stage and size. The distribution of values for ONSD was tested for equality of variances using independent samples t-test. A cut-off value for ONSD was derived using ROC analysis.

RESULTS: The mean difference between ONSD of cases and controls was 0.84 mm (95% CI: 0.61-1.06) and was statistically significant at p < 0.001. Mean ONSD in cases was 5.33 ± 0.66, and in the control group it was 4.49 ± 0.31. The cut-off value for ONSD was taken as 4.57 mm, derived using the ROC analysis (AUC was 0.876 suggesting good diagnostic accuracy). ONSD showed a sensitivity of 87% and a negative predictive value of 89% in predicting CVST. However, we found no statistical significance between ONSD in patients with acute or chronic thrombosis or in those with neuroparenchymal complications.

CONCLUSIONS: ONSD is a valid triage tool with high sensitivity and negative predictive value, and it can be used in the evaluation of CVST.

ABSTRACT

Introduction This study compares the immune response after coronavirus disease 2019 (COVID-19) inactivated virus vaccine between healthy individuals (HI) and patients on hemodialysis (HD). Methods In this cross-sectional, comparative study, the presence or absence of immunoglobulin G (IgG) anti-S antibody and IgG anti-S antibody titer was compared between HI, and patients on HD after two doses of COVID-19 vaccine. Results A total of 81 participants, 50 (61.7%) HD patients and 31 (38.3%) HI, were studied. The mean age was 52.9±12 in HD patients and 42±12.4 in HI. Vaccination responder rates were 80.6% in HI and 72% in HD patients after the first dose (p=0.38) and 93.5% in HI and 94% in HD at the third week of the second dose of the vaccine (p=0.93). The mean IgG antibody titer was 156.3±113.8 in HI and 143.4 ± 117.8 in HD patients (p=0.538) after the first dose and 186.7 ± 97.9 in HI and 180.6 ± 105.8 in HD patients (p=0.552) at three weeks of the second dose. No statistically significant difference was found in antibody titer with respect to gender, age, vaccine (BBIBP-CorV or Conovac), and hypertension. Diabetic HD patients had a lower antibody titer than non-diabetic HD patients (p=0.03) while participants who had a history of COVID-19 infection had a higher IgG titer (p = 0.001). The levels of IgG titer in the same patient increased, corresponding to the doses of vaccine (p <0.001). No HD patient developed COVID-19 infection till the third week of vaccination. Conclusion This study demonstrates a similar humoral response after COVID-19 inactivated virus vaccination in HD patients and HI. The response was lower among diabetic patients on HD and better in those with previous COVID-19 infection.

ABSTRACT

OBJECTIVE: The study aimed to evaluate sexual function before and after inguinal hernia surgery using a standard, internationally approved, patient-administered questionnaire.

METHODS: 57 male inguinal hernia cases operated with the Lichtenstein hernioplasty technique were prospectively included in the study. Patients who agreed to participate in the study had the IIEF (International Index of Erectile Function) scoring system form consisting of 15 questions filled in preoperatively, during the first and sixth months after surgery. Patients’ age, BMI, comorbidity, employment status, hernia type, hernia size, and single or bilateral hernia were recorded. The relationship between these variables was evaluated by statistical analysis.

RESULTS: A statistically significant difference was found in terms of erectile function, sexual desire, intercourse function, and overall satisfaction, when the preop-postop first month, preop-postop sixth month, and postoperative first month-postop six-month scores were compared (p < 0.05).

CONCLUSIONS: Pain and swelling due to an inguinal hernia can negatively affect the sexual functions of the patient, and most of the patients benefit from this after the surgery. Sexual dysfunction may be one of the indications for an inguinal hernia operation.

ABSTRACT

Background Workplace bullying (WPB) is a form of mistreatment toward an individual manifested by physical, verbal, or indirect aggression. Affected victims display a wide range of signs and symptoms that impact their health. This study aimed to investigate the prevalence of aggressive behavior toward healthcare workers and its effects on job satisfaction, general health, and mental health. Methodology An online survey comprising a revised version of the Negative Acts Questionnaire-Revised (NAQ-R) was distributed to the fellows, residents, and nurses working in a tertiary care hospital. The survey collected information regarding the group’s demographics and their exposure to WPB encountered in the work environment while maintaining confidentiality. Survey results were analyzed using SPSS Statistics version 25 (IBM Corp., Armonk, NY, USA). Results Among the 339 participants who filled the survey, 53% of healthcare practitioners in different services had experienced some form of WPB. Among the targeted group, it was noted that female gender (50%), age between 31 and 41 years (57.03%), nurses (51.98%), non-Saudi practitioners (41.94%), and those working in inpatient settings (49.74%) were the most commonly affected individuals in the medical facility. Furthermore, higher bullying prevalence was correlated with lower job satisfaction and mental health levels. Conclusions Age, gender, job, and nationality were factors associated with increased susceptibility to WPB. WPB in any facility is an unfortunate event, especially in a healthcare setting. It affects health practitioners by decreasing job satisfaction, jeopardizing health, and increasing the risk of harm to patients. WPB will eventually have a negative impact on the medical facility and the healthcare sector. Hence, hospital administrations should be alarmed about the rise in WPB, and adequate measures must be taken to deal with the root cause of the problem.

ABSTRACT

Immune checkpoint inhibitors (ICIs) are gradually replacing chemotherapy as the cornerstone of the treatment of advanced malignant tumors because of their long-lasting and significant effect in different tumor types and greatly prolonging the survival time of patients. However, not all patients can respond to ICIs, and even rapid tumor growth after treatment with ICI has been observed in a number of clinical studies. This rapid progression phenomenon is called hyper-progressive disease (HPD). The occurrence of HPD is not uncommon. Past statistics show that the incidence of HPD is 4%-29% in different tumor types, and the progression-free survival and overall survival of patients with HPD are significantly shorter than those of the non-HPD progressor group. With the deepening of the study of HPD, we have established a preliminary understanding of HPD, but the diagnostic criteria of HPD are still not unified, and the addition of biomarkers may break this dilemma. In addition, quite a few immune cells have been found to be involved in the occurrence and development of HPD in the tumor microenvironment, indicating that the molecular mechanism of HPD may be triggered by a variety of ongoing events at the same time. In this review, we summarize past findings, including case reports, clinical trials, and fundamental research; compare the diagnostic criteria, incidence, and clinical prognostic indicators of HPD in different studies; and explore the molecular mechanism and future research direction of HPD.

ABSTRACT

OBJECTIVE: The objective of the study was to compare the motor development of children with Down syndrome (DS) who received physical therapy (PT) and did not receive PT, and to show the effect of PT programs started before the age of one on movement development.

METHODS: The study included aged between 6 and 42 months, 58 children with DS. Children with DS were divided into two groups as receiving PT and non-receiving PT. Children with DS who received PT were further divided into two groups according to the age of starting PT as before and after 1 year of age. Gross motor and fine motor development of the cases were evaluated with Bayley Scales of Infant and Toddler Development III.

RESULTS: Gross motor scaled scores (GM-SS: 3.88±3.46-1.67±1.23), fine motor scaled scores (FM-SS: 4.29±3.24-1.79±0.93), and composite scores (64.4±19.5-50.38±5.38) of PT group were statistically higher than the non-PT group (p<0.05). In addition, GM-SS (5.22±4.23-2.38±1.20), FM-SS; (5.61±3.85-2.81±1.37), and composite scores (72.33±23.85-55.56±5.7) of the cases who started PT before the age of one were statistically higher than those who started after the age of one (p<0.05).

CONCLUSION: Our results revealed that PT especially when started early childhood under had a positive effect on the development of gross and fine motor in children with DS and provided a scientific basis for referring children with DS to PT programs before the age of one. Clinicians should recommend PT for children with DS in the early period.
